Bilco S / SV Series Single Door automatic smoke vents aid Firefighters in bringing a fire under control by removing smoke, heat and gasses from a burning building. Type SV single leaf smoke vents are ideal for applications requiring smaller vent areas, such as elevator shafts or stair wells. Available in galvanized steel or aluminum construction and in a number of standard sizes. Polycarbonate domes covers are also available for natural daylighting. UL rated.

Latch: Positive hold/release mechanism controlled by a single UL-listed 165°F (74°C) fusible link with a separate latching point for each cover. Designed to hold the covers closed against a 90 psf (438kg/m2) wind uplift force. Provided with interior and exterior pull release cables to manually open vent covers.

Operation: Compression springs enclosed in telescopic tubes open covers automatically against a 10 psf (49 kg/m2) snow/wind load when released. Automatic hold-open arms lock the cover in the full open position. Cover is supplied with a shock absorber to assure a controlled rate of opening.
